Abstract
Description
- This application claims the benefit of U.S. Provisional Application No. 62/947,771, filed Dec. 13, 2019, the entirety of which is incorporated herein by reference.
- The present disclosure relates generally to wire harnesses.
- Wire harnesses can include one or more wires that terminate at an electrical connector. The electrical connector enables the wires to securely connect to a device. The one or more wires generally run some distance between the wire harness and the electrical connector to allow the one or more wires to connect to one or more respective slots or connector points of the electrical connector. Thus, there is some portion of the one or more wires that run outside the wire harness and the electrical connector. Without physical support from the wire harness or electrical connector, that portion of the one or more wires can experience mechanical strain due to tension (e.g., curving/bending). Given enough time, the mechanical strain can cause a number of safety and electrical issues such as degradation of the individual insulators of the one or more wires (e.g., exposed wires), cut/broken wires, etc.

Ledge 120(2) may be substantially perpendicular to the side ofbody 102. The inclined surface 115(2) and the ledge 120(2) are configured to snap fit to the one or more structural features of an external surface of an electrical connector. As described in more detail below in connection withFIGS. 5-8 , there is a surface feature on an electrical connector that slides down the inclined surface 115(2) that then becomes lodged beneath the ledge 120(2), thus snap-fitting into thebody 102. - Snap feature 110(2) may further include one or more structural features defining hole 125(2). Hole 125(2) may be a hole in the bottom of
body 102, and may be positioned beneath inclined surface 115(2) and ledge 120(2).

FIG. 3 illustrates a top view of the wire connectorstrain relief apparatus 100. In one example, an electrical connector may be aligned with thesecond end 105 b and snap-fit into the wire connector strain relief apparatus 100 (e.g., the electrical connector may slide into the top of wire connector strain relief apparatus 100). As shown, the generally U-shaped cross section ofbody 102 also provides an open design that allows for visual inspection of the wire connectorstrain relief apparatus 100, electrical connector, wire harness, and/or one or more wires. For example, visual inspection may be made to further ensure that the electrical connector is in the appropriate position (e.g., using locating ribs 130(1) and 130(2)) such that the electrical connector snap-fits to inclined surfaces 115(1) and 115(2). Visual inspection may also be made to monitor the one or more wires for breakages or electrical exposures. -
FIG. 4 illustrates a side cut-away view of the wire connectorstrain relief apparatus 100. As shown, thesecond end 105 b may be relatively deep to enable thesecond end 105 b to accommodate an electrical connector. Thefirst end 105 a may be relatively shallow to enable thefirst end 105 a to accommodate the wire harness and/or one or more wires. Thebody 102 may be made of any suitable material capable of minimizing relative movement between a wire harness and an electrical connector. For instance, thebody 102 may be made of an aircraft-approved material, such as an aircraft-approved plastic (e.g., polycarbonate). In particular, thebody 102 may be engineered to comply with Federal Aviation Administration (FAA) regulations, and may be aerospace rated. -

FIG. 6 illustrates a top view of thesystem 500. The one or more structural features of thesecond end 105 b of the body 102 (e.g., locating ribs 130(1) and 130(2)) are configured to mate with complementary structural features ofelectrical connector 510. In particular, the one or more structural features of the external surface ofelectrical connector 510 may include one or more surface features that is/are complementary to locating ribs 130(1) and 130(2). Locating ribs 130(1) and 130(2) may thus help guideelectrical connector 510 to the appropriate position such thatelectrical connector 510 snap fits into the wire connectorstrain relief apparatus 100. As shown, the generally U-shaped cross section ofbody 102 also provides an open design that allows for visual inspection ofsystem 500. For example, visual inspection may be made to further ensure thatelectrical connector 510 is in the appropriate position with respect to locating ribs 130(1) and 130(2). Visual inspection may also be made to monitor the one ormore wires 520 for breakages or electrical exposures. -
FIG. 7 illustrates a side view ofsystem 500. The one or more structural features of thesecond end 105 b of the body 102 (e.g., snap feature 110(1), locating rib 130(1), locatinggroove 135, etc.) are configured to mate with complementary structural features ofelectrical connector 510. In particular, one or more structural features of the external surface ofelectrical connector 510 may include a surface feature that is complementary to inclined surface 115(1) and/or ledge 120(1). Thus, wire connectorstrain relief apparatus 100 may provide snap-on strain relief for one ormore wires 520. That is,electrical connector 510 may snap into thesecond end 105 b ofbody 102 via snap feature 110(1). This will minimize relative movement betweenwire harness 505 andelectrical connector 510, thereby alleviating mechanical strain on one ormore wires 520. - The one or more structural features of the external surface of
electrical connector 510 may further include one or more surface features that is/are complementary to locating rib 130(1) and/or locatinggroove 135. Locating rib 130(1) and/or locatinggroove 135 may thus help guideelectrical connector 510 to the appropriate position such thatelectrical connector 510 snap fits into snap feature 110(1). -
FIG. 8 illustrates a front view ofsystem 500. As shown, the one or more structural features of thesecond end 105 b of thebody 102 are configured to mate with complementary structural features ofelectrical connector 510. In particular, one or more structural features of the external surface ofelectrical connector 510 may include a surface feature that is complementary to ledges 120(1) and 120(2). That is,electrical connector 510 may snap into thesecond end 105 b ofbody 102 via ledges 120(1) and 120(2). -
Body 102 may include a one-piece design capable of installation without using any tools. For example,electrical connector 510 may be inserted into thesecond end 105 b ofbody 102 to secureelectrical connector 510 via snap features 110(1) and 110(2). However, it will be appreciated that the particular configuration of the structural features configured on the body of a wire connector strain relief apparatus provided herein may depend upon the particular type/model of corresponding electrical connector. For example, snap features 110(1) and 110(2) may be customized forelectrical connector 510. Other electrical connectors may involve other snap feature configurations. Thus, any given electrical connector may utilize the concepts of the uniquely designed strain relief apparatus presented herein. -
